OK. That's still nothing to do with GCC. The repository you linked to
is not GCC code. Crosstool-ng is also not GCC code. Maybe you should
ask on a crosstool-ng list, or ask the author of that change.


> I think in crosstool-ng you can configure RISC-V options using 'ct-ng menuconfig' once you configured then one need to use ct-ng build to to build compiler.  The crosstool-ng will build compiler using the config options, I think there is no Makefile as such for RISC-V. However, I might be wrong.
